    It’s hard to test the whole system with all special tests manually. At least if your project is more than a static website or something similarly trivial.

    That’s why auto tests are there to increase your testing coverage, so that one change won’t break your system in unexpected ways, especially if you do system-wide changes like upgrading your framework or core systems to a new version.
